Chapter
Full-text available
From a phonological point of view, four glides (or approximants) exist in Italian: /j/, /w/, [i̯] and [u̯]. Glides still raise a lot of questions, from the definition of the necessary and sufficient features for their identification (Chitoran, Nevins, 2008), to their characterization at the acoustic and articulatory levels of speech production (Gic...

We will discuss the maintenance of the heritage dialect coronal fricatives in the speech of Italian-Australian trilinguals (dialect/Italian/English) originating from North Veneto, Italy, as compared to the variability found in the productions of comparable Italian-Australian trilinguals originating from Central Veneto. Results on coronal fricatives...
Article
The paper presents the methodology and development tools used in the Multimedia Atlas of Veneto Dialects (AMDV), a linguistic talking atlas, realized by a team of researchers in dialectology, etymology, phonetics and ethnography. The AMDV is mainly focused on the diachronic comparison of the lexical maps of the Sprach- und Sachatlas Italiens und de...
Article
Full-text available
This paper concerns the bimodal transmission of emotive speech and describes how the expression of joy, surprise,sadness, disgust, anger, and fear, leads to visual and acoustic target modifications in some Italian phonemes. Current knowledge on the audio-visual transmission of emotive speech traditionally concerns global prosodic and intonational c...
Conference Paper
Full-text available
In Italian, length contrast is exploited in the consonant system. Previous articulatory studies have focused on the temporal organization of gestures in Italian geminates and on the lower lip kinematics of the singleton/geminate distinction, and have showed that the time interval between the nuclei of two successive syllables does not depend on the...

Full-text available
Glides have been a challenging sound category from both a phonological and phonetic perspective and this is especially true for Italian. In this language four different glides can be distinguished based on their position in a syllable (pre or post-vowel), grouped together as either “semi-consonanti” (/j/ and /w/) or “semi-vocali” (/i/ and /u/). As...

Demetrio Stratos (1945-1979) was a singer known for his creative use of vocal techniques such as diplophony, bi-tonality and diphony (overtone singing). His need to know the scientific explanation for such vocal behaviors, drove him to visit the ISTC in Padova (Institute of Cogni-tive Sciences and Technologies) in the late Seventies. ISTC technical...
Conference Paper
Full-text available
Le differenze nella durata acustica e percettiva dei foni consonantici possono trovare spiegazioni in fatti articolatori di tipo differente, quali le diverse posizioni spaziali dei target e quindi delle ampiezze di movimento, le differenze relative alla velocità dei movimenti e la diversa sincronizzazione di gesti relativi a sequenze di foni. Un ca...

In Italian, length contrast is exploited in the consonant system. Previous articulatory studies have focused on the temporal organization of gestures inItalian geminates and on the lower lip kinematics of the singleton/geminate distinction. In this paper, data on lip and tongue gestures are discussed in order to directly test hypotheses on the gest...
Article
Full-text available
This paper presents an Italian database of acted emotional speech and facial expressions. New data regarding the transition between emotional states has been collected. Although acted expressions have intrinsic limitations related to their naturalness, this method can be convenient for speech and faces synthesis and within evaluation frameworks. Us...
Conference Paper

Nel sistema fonologico dell’italiano si fa un uso pervasivo del contrasto di lunghezza per le consonanti omorganiche in posizione intervocalica interna alla parola. Studi acustici e percettivi (Bertinetto, 1981; Esposito & Di Benedetto, 1999; Zmarich & Gili Fivela, 2005) hanno dimostrato che la durata delle geminate è all’incirca doppia della durat...

The topic of this work is an extension of our previous research on the development of a general data-driven procedure for creating a neutral "narrative-style" prosodic module for the Italian FESTIVAL Text-To-Speech (TTS) synthesizer, and it is focused on investigating and implementing new strategies for building a new emotional FESTIVAL TTS. The ne...
Article
This paper describes how the visual characteristics of some Italian phones (/’a/, /b/, /v/) are modified in emotive speech by the expression of the “big six” emotions: joy, surprise, sadness, disgust, anger, and fear. In this research we specifically analyze the interaction between the articulatory lip targets of the Italian vowel /’a/ and consonan...
Article
Full-text available
A general data-driven procedure for creating new prosodic modules for the Italian FESTIVAL Text-To-Speech (TTS) [1] synthesizer is described. These modules are based on the "Classification and Regression Trees" (CART) theory. The prosodic factors taken into consideration are: duration, pitch and loudness. Loudness control has been implemented as an...

Audio/visual speech, in the form of labial movement and facial ex- pression data, was utilized in order to semi-automatically build a new Italian expressive and emotive talking head capable of believable and emotional be- havior. The methodology, the procedures and the specific software tools util- ized for this scope will be described together wit...

LUCIA, a new Italian talking head based on a modified version of the Cohen-Massaro's labial coarticulation model is described. A semi-automatic minimization technique, working on real cinematic data, acquired by the ELITE opto- electronic system, was used to train the dynamic characteristics of the model. LUCIA is an MPEG-4 standard facial animatio...

Voice quality is recognized to play an important role for the rendering of emotions in verbal communication. In this paper we explore the effectiveness of a sinusoidal modeling process- ing framework for voice transformations finalized to the anal- ysis and synthesis of emotive speech. A set of acoustic cues is selected to compare the voice quality...
Conference Paper
A grammatical component to supply information to a text-to-speech system is presented. It is composed of four modules: a lexicon, a morphological recognizer, a syntactic preanalyzer, a parser. The parser is composed of a bottom-up algorithm implementing a context-free grammar for Italian simply as Recursive Transition Networks (RTN). No conditions...

A system for the automatic translation of any text of Italian into naturally fluent speech is presented. The system, planned for use in a reading machine for the blind, is build up around a Phonological Processor (hence FP) and synthesizes speech-by joining LPC coded diphones. The FP maps into prosodic structures the phonological rules of Italian....

Ifd I really like to remember that Franco was the first person I met when I approached the "Centro di Studio per le Ricerche di Fonetica" and I still have a greatly pleasant and happy sensation of that our first warm and unexpectedly informal talk. It is quite obvious and it seems rhetorical to say that I will never forget a man like Franco, but it...

Speech production in general, and emotional speech in particular, is characterized by a wide variety of phonation modalities. Voice quality, which is the term commonly used in the field, has an important role in the communication of emotions through speech, and nonmodal phonation modalities (soft, breathy, whispery, creaky, for example) are commonl...

1. INTRODUZIONE La qualità dell'emissione vocale, intesa come il risultato delle varie modalità di fonazione possibili, riveste un ruolo importante nella resa delle emozioni nella comunicazione verbale. E' comune osservare, infatti, in corpora di registrazioni di parlato emotivo, casi di fonazione non modale (voce soffiata, sussurrata, laringalizza...

Introduzione Il Canto Difonico (Overtone Singing o Canto delle Armoniche) è una tecnica di canto affascinante dal punto di vista musicale, ma particolarmente interessante anche dal punto di vista scientifico. In effetti con questa tecnica si ottiene lo sdoppiamento del suono vocale in due suoni distinti: il più basso corrisponde alla voce normale,...
